Cameron drew a circle for a craft project. The circumference of the circle was about 47.1 inches, and the diameter of the circle was 15 inches. Which expression best represents the value of p?

Answer : The expression best represents the value of p is,

Step-by-step explanation :

Given:

Circumference of circle = 47.1 inches

Diameter of circle = 15 inches

First we have to calculate the radius of circle.

Now we have to calculate the value of p or π.

Circumference of circle =

where,

r = radius of circle

Circumference of circle = = 47.1 inches

= 47.1 inches

Thus, the expression best represents the value of p is,

answer: standard form is ax^2 + bx + c = 0

step-by-step explanation:

standard form is ax^2 + bx + c = 0

(2x + 1)(x - 2) = 0

distribute to get into standard form

2x^2 - 4x + x - 2 = 0

2x^2 - 3x - 2 = 0

a = 2, b= -3, c = -2

a is your answer

i have no clue at all sorry
